 Package : openh264 CVE ID : CVE-2025-27091 Debian Bug : 1098470

 A heap-based buffer overflow flaw in the decoding functions of openh264, a codec library which supports H.264 encoding and decoding, may allow a remote attacker to cause a denial of service or the execution of arbitrary code if a specially crafted video is processed.

 For the stable distribution (bookworm), this problem has been fixed in version 2.3.1+dfsg-3+deb12u1.

 We recommend that you upgrade your openh264 packages.

 For the detailed security status of openh264 please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/openh264
